Title: Improvements in or relating to detergent compositions in bar form
Inventor: WARD NORMAN ERNEST
IPC: C11D17/00
Filed: 1960-08-31
Abstract: A detergent composition in bar form comprises a mixture of preformed soluble soap and at least one preformed alkaline earth metal, magnesium, zinc or aluminium salt of a sulphuric acid derivative of general formula RCO.O(CH2)nSO4H in which RCO is a C10-18 fatty acyl radical, n is 1-3, and the group (CN2)n may carry not more than one unesterified hydroxyl group.  The mixing of the soap and salt is carried under conditions such that exchange of cations does not take place, i.e. with insufficient water to make the mixture fluid, or if more water than this is present the mixing is achieved quickly and the product dried immediately.  The soap may be a conventional alkali metal soap, e.g. one derived from a mixture of tallow with coconut or palm kernel oil, while a suitable salt is calcium lauryl monoglyceride sulphate.  A small proportion of free saturated C10-18 fatty acid (e.g. hydrogenated fatty acids comprising 50% coconut and 50% tallow) may be present, as also may be perfume, colour, opacifiers, superfatting agents, and germicides.

Title: Hydraulic tools for use in drill strings
IPC: E21B31/113
Filed: 1973-03-20
Abstract: 1426481 Boring earth &c LEE-MASON TOOLS LTD 20 March 1973 13212/73 Heading E1F A hydraulic tool for incorporation into a drill string to free the string when stuck by jarring upwardly or bumping downwardly, comprises a barrel 6 and a mandrel 5 received therein in spaced relationship to define a bumper hydraulic chamber 15, Fig. 1b, and a jar hydraulic chamber 16, and abutment means 21, 22, Fig. 1a, and 6a, 19. The mandrel 5 is held from rotating relative to the barrel 6 by means of male and female splined members 2 and 3, respectively. Relative longitudinal movement of the barrel and mandrel is possible between a fully-contracted position (as shown) where impact faces 21, 22 abut to bump the string downwardly, and a fully-extended position (Figs. 3a to 3c not shown) where impact faces 6a, 19 abut to jar the string upwardly. Intermediate the chambers 15, 16 is provided a reduced section 10 having grooves 55 in the wall thereof, and the mandrel is provided with a slidably-mounted valve sleeve 20 having grooves (52), Fig. 8 (not shown), in its upper edge. In order to jar, the drilling string and therefore the mandrel are drawn upwardly until the valve sleeve 20 enters the section 10 whereupon friction forces the sleeve downwardly into sealing contact with a valve seat 18 and fluid flow between the sleeve and mandrel is blocked. As the mandrel continues upwardly a restricted passage exists between the sleeve and section 10 which causes an increase in fluid pressure in jar chamber 16, and when the sleeve moves out of section 10 and into chamber 16 the mandrel jerks forwardly until impact faces 6a, 19 slam together. In order to bump, the drill string is released and the mandrel drops unseating valve sleeve 20 thereby allowing fluid flow between the sleeve and mandrel allowing the sleeve 20 to drop easily through reduced section 10 until impact faces 21, 22 slam together. To remove mud etc. from between the splines of the female member 3 during contraction of the tool a frusto-conical base 28 and inclined ports 27 are provided. The mandrel in the contracted condition of the tool extends into a sub 7, Fig. 1c (not shown), the lower end of the sub being connected to the lower section of drill string. Fixed seals 13 and a floating seal 14 responsive to mud pressure are provided between the barrel 6 and mandrel 5.

Title: Improvements in or relating to electric pulse counting apparatus
Filed: 1960-04-13
Abstract: 877,986. Counting-apparatus; electric digital-data-storage apparatus. LANDIS & GYR A.G. April 13, 1960 [April 17, 1959], No. 13215/60. Class 106 (1). An arrangement for counting on a single counter pulses from a plurality of sources comprises a magnetic core storage device for each source, the cores being scanned successively to cause activated cores to produce an output pulse which is passed to the counter. As shown for pulses from two sources such as electricity meters, a pulse to be counted appears across terminals 1, 2, and in response to this pulse a core 4 produces a short pulse which switches a storage core 10 via a circuit including a rectifier 8. A winding 11 on the core 10 is connected to a winding 13 on a read-out core 14, a second winding 15 or the core 14 being connected to a capacitor 16 which is periodically discharged, through a photo-resistor 20, the photo-resistors 20 for the two pulse sources 1, 2 being scanned sequentially by means of a rotating cylinder 21 having a window 22 illuminated interiorly by a radiation source 23. The discharged capacitor is immediately recharged by a source 18, 19, the read-out core 14 being thus switched first in one direction and then in the other direction. The first pulse thereby produced is supplied to the winding 11 on the core 10. If the core 10 has been already magnetized by a pulse on the winding 9, it is now reversed to produce a pulse which charges a capacitor 26 which then discharges through a circuit comprising a magnetic amplifier 30 to step on a counter 33. To ensure that if a counting pulse and a read-out pulse arrive at the core 10 simultaneously, the counter 33 is nevertheless stepped on, a further circuit including a core 37 is provided, the pulse produced in the winding 13 of the read-out core 14 when the capacitor 16 discharges being supplied also to a winding 36 of the core 37, which is thereby switched. The next impulse, produced by the charging of the capacitor 16, flows through a winding 38 to reverse the core 37 the voltage thereby produced in the winding 38 preventing the capacitor 26 charging from this impulse when the windings 9, 11 of the core 10 are pulsed simultaneously the core 37 is not switched and the next pulse produced by capacitor 16 charging is capable of charging the capacitor 26 to operate the counter 33. Modifications.-The rotating cylinder 21 and source 23 may be replaced by contacts to produce the pulses for triggering the core 10. Also, the cores 4, 37 and associated circuitry can be omitted. In a second embodiment (Fig. 2, not shown) the photo-resistances are replaced by transistors, each transistor becoming conducting when an armature on a rotating drum approaches a magnetic core associated with the transistor.

Title: Improvements in trigger mechanisms for recoiling automatic guns of the open breech type
IPC: F41A19/31
Filed: 1955-05-11
Abstract: 776,580. Automatic guns. BREVETS AERO-MECANIQUES SOC. ANON. May, 11, 1955 [May 21, 1954], No. 13653/55. Class 92. Relates to trigger mechanisms for recoiling automatic guns of the open breech type, the gun proper being mounted movably on a fixed support with respect to which it recoils on firing against the action of a damping system. According to the invention the trigger mechanism includes a locking device for keeping the sear out of the path of the breech block, the locking device being mounted on the fixed support and controlled by a part which participates in the recoil movement of the gun with respect to its support, the arrangement being such that the release of the sear to stop firing is only possible during periods corresponding to the end of the return movement of the gun into firing position and the beginning of its recoil stroke, these periods being when release of the sear will subsequently produce a satisfactory engagement of the sear with the breech block. As shown in Fig. 2 the trigger mechanism comprises a rod 9 controlled by the trigger proper and hinged to a control lever 10, 11 pivoted at 12 to the gun support 3. A second lever 13 pivoted at 14 to the breech casing 2 has at one end a roller 15 running on a ramp 16 on the lever arm 11, the other end of the lever 13 carrying a finger 17 engaging a groove 18 in the spring-urged sear 4 pivoted at 5 to the breech casing 2. During firing the ramp 16 is parallel to the movement of recoil of the gun. The locking device is formed by a fork lever 20 pivoted at 19 to the gun support 3 and urged to a vertical position by a spring 22, in which position and in the firing position of ramp 16 shoulders 21 on the lever 20 engage under side projections 23 on the end of the lever arm 11 ; anti-clockwise movement of the lever 13 is thus prevented and hence the sear 4 is held out of the path of the breech block 1 against the action of its spring 7. Release of the sear to stop firing during a period of the gun recoil which will ensure effective engagement of the sear with the notch 8 in the breech block 1, is effected by an abutment 24 carried by the breech casing 2 and positioned so that it keeps lever 20 away from the vertical position during the end of the recoil stroke of the gun and at the beginning of its recoil stroke. When this is so, the shoulders 21 are disengaged from projections 23 and control lever 10, 11 can be actuated by the trigger rod 9 as shown in Fig, 4, to permit the lever 13 and sear 4 to come into active position.
